Several leftist guerrilla groups attempting to overthrown the pro-Western regime of ShahMohammad Reza Pahlavi were notable and active in Iran from 1971 to 1975. The groups shared a commitment to armed struggle, but differed in ideology. Most were Marxist in orientation, but the largest group — People''s Mujahedin of Iran — was founded as an Islamic socialist organization.

While the guerrilla movement did not lead the revolution that overthrew the Pahlavi regime, four guerrilla organizations — the Feda''i, the pro-Tudeh Feda''i Munsh''eb, the Islamic Mujahedin and the Marxist Mujahedin — are said to have "delivered the regime its coup de grace," in the street fighting of February 9-11 1979.

small Marxist groups. These included both independent groups, such as the Sazman-i Azadibakhshi-i Khalqha-yi Iran (Organization for the Liberation of the Iranian Peoples), Gorueh-i Luristan (Luridtan Group), and Sazman-i Arman-i Khalq (Organization for the People''s Ideal); and cells belonging o political parties advocating armed struggle —the Tofan group, the Revolutionary Organization of the Tudeh party, the Kurdish Democratic party, and a new left organization named Grouh-i Ittehad-i Komunistha (Group of United communists). Moreover, some of the feda''is had at the time of their death joined the Tudeh party.

Guerrilla groups formed it is believed, because the non-armed, mass-based communist Tudeh party was under such intense repression it was unable to function, while in the outside world guerillas Mao Zedong, General Vo Nguyen Giap and Che Guevara were having, or had had, much success. The Iranian guerrilla strategy has been described by Abrahamian as "heroic deeds of violent resistance to break the spell of government terror".

In a situation where there are no firm links between the revolutionary intelligentsia and the masses, we are not like fish in water, but rather like isolated fish surrounded by threatening crocodiles. Terror, repression, and absence of democracy have made it impossible for us to create working-class organizations. To break the spell of our weakness and to inspire the people into action we must resort to revolutionary armed struggle...

The background of the guerrillas was overwhelming educated middle class. From 1971 to 1977 an estimated 341 of them were killed, of whom over 90% of those for whom information could be found were intellectuals.

History

The event from which most historians mark the beginning of the guerrilla era in Iran was the February 8, 1971 attack on a gendarmerie post at Siahkal on the Caspian Sea. Guerillas killed three policemen and freed two previously arrested guerrillas.

The guerrilla organizations were quite active in the first half of the 1970s. In the two and half years from mid 1973 through 1975, three United States colonels, a Persian general, a Persian sergeant, and a Persian translator of the United States Embassy were all assassinated by guerrilla groups. On January 1976 eleven persons sentenced to death for these killings.

By the second half of the 1970s, however, the groups were in decline, suffering from factionalism and government repression.

The People''s Mujahedin of Iran (Sazman''i Mujahedin-i Khalq-i Iran) was in the middle of an internal debate over whether to continue armed struggle, and the group''s own publications report few actions in 1978 and a `relative silence` as the number of actions decreased after June 1978.

The Iranian People''s Sacrificing Guerrillas (Cherik''ha-ye Feda''i-ye Khalq-e Iran), according to one of the group''s leaders, `disintegrated and disappeared` after `the blows of 1976`, `set itself principally to protecting itself,` and engaged only in `scattered actions` to show that it still existed. Only a few dozen members remained at large. Ideologically, the group decided that objective conditions for revolution didn''t exist, and as the Islamist movement escalated, the organization claimed credit for relatively few actions - one in the summer 1977, two in early 1978, and five in the summer of 1978, according to the group''s pronouncements. At the end of the year, with membership presumably growing, the organization picked up its pace, claiming credit for a half-dozen actions in December 1978 and a dozen in January 1979.

Iranian Revolution

By late 1978 however, the massive demonstrations, return of oppositionists from abroad, and pressure on the monarchy''s security forces from the revolutionary movement revived the groups. Guerilla groups became active "both in killing Iranian military and police leaders and participating in oppositional demonstrations ... in the course of 1978 ... the Fedaiyan and the Mojahedin were able to ... become sizable movements, largely of young people."

Following the Iranian Revolution most of the groups were successfully suppressed by the Islamic Republic. People''s Mujahedin of Iran (PMoI) continued but moved to Iraq which was at war with the Islamic Republic. The (PMoI) currently describes itself as a non-violent, democratic opposition group.
